The front, front side, and side curtain
airbags are deployed according to the
direction and severity of impact. Both side
curtain airbags are deployed in a rollover.
The airbag system includes:
aTwo SRS (Supplemental Restraint System)
front airbags. The driver's airbag is stored
in the center of the steering wheel; the
front passenger's airbag is stored in the
dashboard. Both are marked SRS
AIRBAG.
bTwo side airbags, one for the driver and
one for a front passenger. The airbags are
stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG.
cTwo side curtain ai rbags, one for each
side of the vehicle. The airbags are stored
in the ceiling, above the side windows.
The front and rear pillars are marked

uuAirbags uFront Airbags (SRS)
48
Safe DrivingFront airbags are designed to inflate du ring moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won't interfere with the driver's visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until th ey see them lying in front of them.
■Operation
■How the Front Airbags Work1How the Front Airbags Work
Although the driver's and fr ont passenger's airbags
normally inflate within a spli t second of each other, it
is possible for only one airbag to deploy. This can
happen if the severity of a collision is at the margin,
or threshold, that determines whether or not the
airbags will deploy. In such cases, the seat belt will
provide sufficient protec tion, and the supplemental
protection offered by the airbag would be minimal.

■When front airbags should not deploy
Minor frontal crashes: Front airbags were designed to supplement seat belts and
help to save lives, not to prevent minor scrapes, or even broken bones that might
occur during a less than mode rate-to-severe frontal crash.
Side impacts: Front airbags can provide protection when a sudden deceleration
causes a driver or front passenger to move towards the front of the vehicle. Side
airbags and side curtain airbags have been specifically designed to help to reduce
the severity of injuries that can occur du ring a moderate-to-severe side impact which
can cause the driver or passenger to move towards the side of the vehicle.
Rear impacts: Head restraints and seat belts are your best protection during a rear
impact. Front airbags cannot provide any significant protection and are not designed
to deploy in such collisions.
Rollovers: Seat belts, and in vehicles equipped with a rollover sensor , side airbags,
and side curtain airbags offer the best protection in a rollover. Because front airbags
could provide little if any protection, they are not designed to deploy during a
rollover.
■When front airbags deploy with little or no visible damage
Because the airbag system senses sudden deceleration, a strong impact to the
vehicle framework or suspension might caus e one or more of the airbags to deploy.
Examples include running into a curb, the edge of a hole, or other low fixed object
that causes a sudden deceleration in th e vehicle chassis. Since the impact is
underneath the vehicle, damage may not be readily apparent.
■When front airbags may not deploy , even though exterior damage
appears severe
Since crushable body parts absorb crash energy during an impact, the amount of
visible damage does not always indicate proper airbag operation. In fact, some
collisions can result in severe damage but no airbag deployment because the airbags
would not have been needed or would not have provided protection even if they
had deployed.

Safe DrivingYour front airbags have advanced features to help reduce the likelihood of airbag
related injuries to smaller occupants. The driver’s advanced front airbag system
includes a seat position sensor.
If the seat is too far forward, the airbag
inflates with less forc e, regardless of the
severity of the impact.
The passenger’s advanced front airbag system
has weight sensors.
Although we recommend against carrying an
infant or small child in front, if the sensors
detect the weight of a child (up to about 65
lbs or 29 kg), the syst em will automatically
turn off the passenger's front airbag.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver’s seat position
sensor, the SRS indicator wi ll come on and the airbag
will inflate with full (normal) force, regardless of the
driver’s seating position.
For both advanced front airbags to work properly:
•Do not spill any liquid on or under the seats.•Do not put any object under the passenger’s seat.
•Make sure any objects are positioned properly on
the floor. Improperly pos itioned objects can
interfere with the advanced airbag sensors.
•All occupants should sit upri ght and wear their seat
belts properly.
•Do not place any cover over the passenger side
dashboard.

Safe Driving
Side Airbags
The side airbags help protect the torso and pelvis of the driver or a front passenger
during a moderate-to-severe side impact.
The side airbags are housed in the outside
edge of the driver’s and passenger’s seat-
backs.
Both are marked SIDE AIRBAG.
When the sensors detect a moderate-to-
severe side impact, the control unit signals the
side airbag on the impact side to immediately
inflate.
■Housing Locations
1 Side Airbags
Make sure you and your front seat passenger always
sit upright. Leaning into the path of a side airbag can
prevent the airbag from deploying properly and
increases your risk of serious injury.
Do not attach accessories on or near the side airbags.
They can interfere with the proper operation of the
airbags, or hurt someone if an airbag inflates.
Do not cover or replace the front seat-back covers
without consulting a dealer.
Improperly replac ing or covering front seat-back
covers can prevent your si de airbags from properly
deploying during a side impact.

Safe Driving
■When a side airbag deploys with little or no visible damage
Because the airbag system senses sudden acceleration, a strong impact to the side
of the vehicle’s framework can cause a side airbag to deploy. In such cases, there
may be little or no damage, but the side impact sensors detected a severe enough
impact to deploy the airbag.
■When a side airbag may not deploy, even though visible damage appears
severe
It is possible for a side airbag to not deploy during an impact that results in
apparently severe damage. This can occur when the point of impact was toward the
far front or rear of the vehicle, or when the vehicle’s crushable body parts absorbed
most of the crash energy. In either case , the side airbag would not have been
needed nor provided protection even if it had deployed.

■Passenger Airbag Off Indicator1Passenger Airbag Off Indicator
To ensure the passenger is detected properly, confirm
that:
•There is no child seat or other object pressing
against the rear of the seat-back.
•There is no rear passenger pushing or pulling on
the back of the front passenger’s seat.
•The front seat or seat-b ack is not forced back
against an object on the s eat or floor behind it.
•There is no object placed under or beside the front
passenger’s seat.
•The occupant is sitting in an upright position and
the seat back is not excessively reclined.
•The occupant is not leaning against the door or
center console.
•The occupant’s feet are placed on the floor in front
of them.
•There are no objects ha nging from the front
passenger’s seat.
•Only small, lightweight objects are in the seat-back
pocket.
The passenger airbag off indicator may come on and
go off periodically if the tota l weight on the seat is
near the airbag cutoff threshold.
Have your vehicle checked by a dealer as soon as
possible if:
•All of the above conditions are met, and the
indicator comes on with an adult seated in the
front passenger seat.
•The seat is empty and the indicator is off.
Do not allow an adult passe nger to ride in the front
seat when the indicator is on.
